Fig. 14.3.-1 Analog inputs commissioning page for the 3CT, 3VT, 1VT, 1CT module
With sensor inputs, the displayed values are the voltages read by the analog
channels. For example, by using the voltage divider 10.000/1 applying 20 kV on the
sensor, the measurement will show 2 Volt. For the current sensor 80 A/150 mV,
applying 80 Amp on the sensor the measure will be 0.150 Volt.
